由于使用 ParallelTask 和 ConcurrentStack 的单声道导致 Android 崩溃
Crash on Android arising from mono for using ParallelTask and ConcurrentStack usage
描述
我从单声道中遇到崩溃，从徽标中我没有得到任何我可以在代码中更改的具体内容
[] * Assertion at /Users/builder/jenkins/workspace/archive-mono/2019-06/android/release/mono/metadata/sgen-tarjan-bridge.c:1140, condition `xref_count == xref_index' not met, function:processing_build_callback_data, xref_count is 47 but we added 45 xrefs
[libc] Fatal signal 6 (SIGABRT), code -6 (SI_TKILL) in tid 26216 (Thread Pool Wor), pid 25949 (ileapp_colorpoc)
不确定根本原因是什么，因为相同的代码可以正常运行 2 次迭代。我将所有内容都包装在 try catch 中，看看是否有我可以捕获的异常。垃圾收集器似乎有问题

代码
System.Collections.Concurrent.ConcurrentStack<MyClass1> myobjs = new System.Collections.Concurrent.ConcurrentStack<MyClass1>();
System.Threading.Tasks.Parallel.ForEach(viewModel.Searchobjs, (item) =>
{
if (item.objID != obj.objID)
{
myobjs.Push(new MyClass1(item, diff.Diff));
}
});
if (myobjs.Count > 0)
{
List<MyClass1> closeobjs = myobjs.OrderBy(x => x.Diff).ToList();
foreach (var item in closeobjs)
{
if (!objs.ContainsKey(item.objID))
{
objs.Add(item.objID, item);
break;
}
}
}
我注意到这可能是由于使用 ParallelTask 造成的，它可能会消耗更多内存并产生更多需要释放的垃圾。
我也在同一代码领域使用 Dictionary

不应从单声道崩溃
实际行为
崩溃
我也在 Xamarin.Forms/Github 上提出了问题。如果有人遇到这个问题并解决了，请帮助。
如果有人遇到同样的问题，解决方案是将调试器类型从 Tarjan 切换到 New
创建文件Environment.txt并将属性Build Action设置为AndroidEnvironment
内容将是
MONO_GC_PARAMS=bridge-implementation=new,nursery-size=128m,soft-heap-limit=512m
- 确保您的 android 项目
.csproj 有类似 的行
<ItemGroup>
<AndroidEnvironment Include="Environment.txt" />
</ItemGroup>
请注意，我必须延长软堆限制，因为我的应用程序的默认值很低
- 运行 应用程序

代码
System.Collections.Concurrent.ConcurrentStack<MyClass1> myobjs = new System.Collections.Concurrent.ConcurrentStack<MyClass1>();
System.Threading.Tasks.Parallel.ForEach(viewModel.Searchobjs, (item) =>
{
if (item.objID != obj.objID)
{
myobjs.Push(new MyClass1(item, diff.Diff));
}
});
if (myobjs.Count > 0)
{
List<MyClass1> closeobjs = myobjs.OrderBy(x => x.Diff).ToList();
foreach (var item in closeobjs)
{
if (!objs.ContainsKey(item.objID))
{
objs.Add(item.objID, item);
break;
}
}
}
我注意到这可能是由于使用 ParallelTask 造成的，它可能会消耗更多内存并产生更多需要释放的垃圾。
我也在同一代码领域使用 Dictionary

我也在 Xamarin.Forms/Github 上提出了问题。如果有人遇到这个问题并解决了，请帮助。
如果有人遇到同样的问题，解决方案是将调试器类型从 Tarjan 切换到 New
创建文件
Environment.txt并将属性Build Action设置为AndroidEnvironment内容将是
MONO_GC_PARAMS=bridge-implementation=new,nursery-size=128m,soft-heap-limit=512m
- 确保您的 android 项目
.csproj有类似 的行
<ItemGroup>
<AndroidEnvironment Include="Environment.txt" />
</ItemGroup>
请注意，我必须延长软堆限制，因为我的应用程序的默认值很低
